LifeScore is unique in the quality of its musical building blocks, its methods for representing and applying compositional ideas, and its ability to adapt to the listener’s environment and inputs in real-time with music that sounds as if it were written for that purpose. The result is the best of human and machine contributions: human professionals create music that is of the highest quality recorded music, and the machine assembles it into endlessly varying renditions that can be unique on every listen and play for long durations without sounding repetitive or synthetic.
